Four-point characteristic

The four-point characteristic allows you to define your own heating characteristic. It is de-
fined by four points for the outdoor temperature, flow temperature, reduced flow temperature
and return flow temperature. The 'Max. flow temperature' and 'Min. flow temperature' pa-
rameters mark the upper and lower limits of the flow temperature.

Note
− The 'Day set point' and 'Night set point' parameters are no longer available when the four-
point characteristic has been selected when no additional functions (e.g. optimization,
flash adaptation) have been selected.
− The four-point characteristic function can only be activated when the adaptation function is
not active (CO1, 2 > F08 - 0).
